The Federal Aviation Administration’s (FAA) Next Generation Air Transportation System (NextGen) program is a long-term modernization and transformation of the current National Airspace System (NAS) into a more efficient and coordinated decision-making system. In order to test the key concepts and methods proposed by FAA and affiliated standard organizations such as RTCA (Radio Technical Commission for Aeronautics), Modeling and Simulation (M&S)-based demonstration of the solutions are employed in the early stages for the verification and validation of concepts and their technologies. With the help of model-based and simulation-based engineering, large-scale systems integration and demonstrations take place seamlessly. This demands for common understanding of simulation scenarios, allowing for cross-platform interoperability. A major challenge facing the development and testing of the demonstrations is the lack of standard scenario definition language bridging the gap between the operational team (controllers, pilots, and dispatchers) and the engineering community. This paper will tackle aviation scenario generation challenges using the recently proposed Aviation Scenario Definition Language (ASDL). ASDL aims at providing a standard scenario specification that leads to a common mechanism for verifying and executing aviation scenarios, effective sharing of scenarios among various simulation environments, improve the consistency among different stakeholders and entities and enable the reuse of scenario specifications. Based on Domain-Specific Language (DSL) design methodologies, current version of ASDL provides a well-structured definition language to define various flight operations scenarios. In this paper, a number of scenarios that have been implemented in previous FAA funded projects, including scenarios of 4 Dimensional trajectory operations as well as unmanned aerial system operations will be presented and an equivalent ASDL generated scenario script will be pro

Keeping track of blood glucose levels non-invasively is now possible due to diverse breakthroughs in wearable sensors technology coupled with advanced biomedical signal processing. However, each user might have different requirements and priorities when it comes to selecting a self-monitoring solution. After extensive research and careful selection, we have presented a comprehensive survey on noninvasive/pain-free blood glucose monitoring methods from the recent five years (2012-2016). Several techniques, from bioinformatics, computer science, chemical engineering, microwave technology, etc., are discussed in order to cover a wide variety of solutions available for different scales and preferences. We categorize the noninvasive techniques into nonsample- and sample-based techniques, which we further grouped into optical, nonoptical, intermittent, and continuous. The devices manufactured or being manufactured for noninvasive monitoring are also compared in this paper. These techniques are then analyzed based on certain constraints, which include time efficiency, comfort, cost, portability, power consumption, etc., a user might experience. Recalibration, time, and power efficiency are the biggest challenges that require further research in order to satisfy a large number of users. In order to solve these challenges, artificial intelligence (AI) has been employed by many researchers. AI-based estimation and decision models hold the future of noninvasive glucose monitoring in terms of accuracy, cost effectiveness, portability, efficiency, etc. The significance of this paper is twofold: first, to bridge the gap between IT and medical field;and second, to bridge the gap between end users and the solutions (hardware and software). © 2008-2011 IEEE.

The riseofmodeling and simulation has been phenomenalin aviationasa swift, accurate, and cost-effective method for experimentation and training. However, there still exists a lack of common understanding and standardized practices in the simulation scenario development process. This paper presents a detailed overview of the Aviation Scenario Definition Language, which provides a standard scenario specification mechanism in the aviation domain. The Aviation Scenario Definition Language provides a well-structured definition language to formally specify a complete flight simulation scenario. This paper provides the technical details of the Aviation Scenario Definition Language and its underlying Simulation Interoperability Standards Organization standard base object model. Acase study for unmanned aerial vehicle flight is presented to demonstrate the capabilities of the Aviation Scenario Definition Language in automatically generating simulation scenario scripts for a target flight simulator. © 2018 by the American Institute of Aeronautics and Astronautics, Inc.

Distributed manufacturing operations include cyber-physical systems vulnerable to cyber-attacks. Long time not considered a priority, cybersecurity jumped to the forefront of manufacturing concerns due to the need to network together legacy, newer equipment, and entire operation centers. This paper proposes trustworthiness solutions for integrated manufacturing physical-cyber worlds, where trustworthiness is defined to complement system dependability requirements with cybersecurity requirements, such that the resulting manufacturing cyber-physical system delivers services that can justifiably be trusted. Acknowledging the inevitability of cyber-attacks, the paper models the cybersecurity component using the resilient systems framework, where system resilience is viewed as preservation of a required state of cybersecurity. © 2017 The Authors

The Inphase/Quadrature phase (I/Q) imbalance is an inevitable problem in wireless communication systems due to imperfections in the transceiver hardware. In this paper, we investigate the effect of I/Q imbalance in Quadrature Amplitude Modulation (QAM) communication systems adopting multiantenna receivers and the IF (Intermediate Frequency) architecture. Two application scenarios are studied: adaptive beamforming and Blind Source Separation (BSS)-based multiuser detection. For both applications, after analyzing the interference introduced by the transceiver I/Q imbalance, we illustrate that, like systems adopting the zero-IF architecture, straightforward digital signal processing algorithms can be applied in systems with the IF architecture as well to correct the effect of I/Q imbalance. The differences between systems adopting the zero-IF and IF architectures are clarified. computer simulation results are presented to confirm the conclusions of theoretic analysis.

In this paper, we explore the benefits of teaching heavyweight process life cycle models to young software engineering students to better prepare them in the use of agile methods. The benefits of agile methods compared to process-heavy models include the ability to respond faster to the changing needs of customers and the short feedback loop between customers and developers. Since agile methods depend significantly on the competence of the individual, teaching traditional approaches (e.g. waterfall) can be advantageous to the understanding of students about what the major activities associated with software development are, by providing a well-defined structure that naturally aligns with the novice student. Towards this goal, we conducted a survey with different types of software engineers, ranging from novice undergraduates to software engineering professionals. The survey provides data on the exposure of traditional and agile process, the level of experience in using traditional and agile process models, and the perceived most optimal learning sequence. Based on the analysis of the collected data, we argue that teaching traditional software engineering process-oriented approaches prior to introducing agile methods, is highly beneficial to students' understanding and optimal use of agile techniques.

As one of the main focuses of Federal Aviation Administration (FAA) Academy, Air Traffic Control (ATC) training program heavily relies on simulation-based training and is constantly looking into optimizing the use of such technologies. On the other hand, ATC simulation scenarios are not only used for training purposes, but also are key components for conducting human performance experiments. From a recent visit at the FAA Academy, it is well apparent that there is an immediate need for a diverse pool of ATC training scenarios available to trainees off-site. Currently, training scenarios are generated manually from a subject-matter-expert’s (i.e. controllers) oral or written briefing. The effort in extracting and verifying operational scenarios and translating them into a machine-understandable language is rather cumbersome and currently conducted completely manual. To address these challenges, here we propose to develop a scenario exploration technology that provides a platform for FAA Academy trainees and instructors to exercise variety of scenarios in the ATC domain. The proposed technology provides a platform for instructors and trainees to explore various training exercises. By taking a model-driven approach and extending the recently proposed domain-specific Aviation Scenario Definition Language (ASDL), we provide ATC scenario specification and exploration platform to easily create a variety of ATC scenarios. Similar to ASDL approach, we first define an ontology for ATC extension, then specify scenario logic using a formal specification language such as statechart, and finally, include a metamodel to allow for scenario modeling. © 2018, American Institute of Aeronautics and Astronautics Inc, AIAA.

Aviation industry is characterized by its broad utilization of modeling and simulation starting from concept demonstration to operator training. Scenario development is an important aspect of any simulation study, however, the community is still lacking of a common understanding and standardized practices. This leads to degraded interoperability and shareability. The American Institute of Aeronautics and Astronautics (AIAA) Modeling and Simulation Technical Committee (MSTC) is recently trying to create a synergy towards development of a standard scenario definition language for aviation by conducting sessions and panel discussions in conferences and launching a working group. This paper presents the recap of the panel discussion that has been carried out as a part of the invited session "Aviation Simulation Scenario Development" in AIAA Modeling and Simulation Technologies Conference of Scitech 2017. © 2018, American Institute of Aeronautics and Astronautics Inc, AIAA.

Future IoT is expected to get ubiquitous connection and access in a global scale. In the meantime, with the empowered communications capability for IoT devices, IoT will evolve to be highly autonomous, even under the help from infrastructure, and thus will gradually establish the smart IoT community. One of the major challenges imposed on the smart IoT communities is the socialization of IoT communications, because massive IoT accesses make centralized control very hard and also face the shortage of spectrum resources. Towards these issues, we in this article first present the overview and discussions on social features affecting connections among devices. Then, we motivate studies on the statistical characteristics of social features for connections among devices towards smart IoT. We further propose the queuing model under unified asymptotic analyses framework to characterize the statistical social features, with emphases on typical social metrics such as credit, reputation, centrality, etc. How to apply these features for network optimization is further suggested. Finally, we share our opinion on the open problems of social-aware design towards future smart IoT. Copyright © 2018, The Authors. All rights reserved.
